The machine 1 21 herein shown is of the Owens typeand comprises a mold carriage 23 rotating continuously about the centralvertical axi of the mac'hine.

The apparatus for receiving thesebottles at 35 time, although the numberobviously may be varied] The bottles as they are dis charged froin'tliemolds of the blowingnim chine drop onto carriers25, each of whichcoinprisesa pair of plat'fori'ns 2G and 27. These platforms are dividedinto individual compartments by spacing stripsorpartitions 28 to receivethe. individual bottles and prevent them, from coining in contact witheach other before they have cooled; siifliciently to prevent'stickiiigfi Asbestos strips 19 are renovably" held in place on thecarriers by pivoted we1ghts18 and serve as buffers foi" the bottles. Asherein shown, two carriers at oppositeends of a horizontally disposedarm or carriage29 mounted on a-vertical 'drixl le shaft 30 forcontinuous rotation therewit."'" r are provided, the same being.supported The means for driving'the shaft comj prises a rin'ggear'32 onthe machine carriage 23, which gear drives a pinion 33 one verticalshaft 34. Saidshaft extends downward through a gear case 35 mounted onthe base 36 of the blowing machine. Vithin the gear case'isa gear 37(Fig. 6)"whic li drives .43 on the shaft'39 whichgear meshes with a gear'44Ion the shaft 30',

I The shaft; '39 includes universal joints and 46 and tel escopingsections between said joints to permit adjustment of the frame 42 towardand I from thebottle blowing machine. 'lhefraine 42 is supported on theouter .end' of an arm 47 secured to the machine base" 36. The frame 42isadjustable by means-of a rack 48 (Fig. 4) secured to the undersidethereof 1104' and operated by a pinion 49 on a shaft 50 mounted in thearm 47. A hand Wheel 51 is attached to the shaft 50 for rotating it toadjust the frame l? toward or from the blowing machine for bringing thecarriers into proper position with respect to the molds. A spring detent52 (Fig. i) holds the pinion in its adjusted position.

The carriers 25 are mounted for tilting movement on the arm 20. Topermit such movement of a carrier, a rock shaft is journaled in the endof the arm 29 and the platforms 26 and 27 are fixed to said rock shaftat opposite sides of the arm. The latter is bifurcated to receive a rockarm 54 fixed to the shaft 53 and carrying a cam engaging roll which runson a stationary cam 56 to control the tilting movements of the carrier.The arm 29 on which the carriers are mounted has an adjustable COI1-nection with the continuously rotating shaft 30, con'iprising a wormgear 57 fixed to said shaft and meshing with a worm on a shaft 58journalled in the arm 29 and provided with a hand wheel 59. By rotatingthe hand wheel, the arm 29 is rotatively adjusted on the shaft 30 andthe carriers 25 thereby ad justed horizontally to the position requiredto insure the bottles being dropped in pro er position on the platforms.It will be understood that the gearing for driving the carriers is soproportioned that one of the carriers is brought into register with eachhead 24 as the latter reaches its discharging position.

The cam 56 comprises a dwell portion 60 by which each carrier 25 is heldin an upwardly and outwardly inclined position to receive the bottles.As the carrier travels toward discharging position. the cam roll isbrought to an intermediate section 61 of the cam which permits thecarrier to swing downwardly to an approximately horizontal position.When the section 62 of the cam is reached, the carrier swings downwardso that the bottles are permitted to slide by gravity therefrom onto aninclined chute 63. A stationary shield 6d may be provided and arrangedto prevent a premature discharge of the bottles from the carrier.

The bottlesslide down the chute 63 and drop off the forward end of thechute onto the horizontal conveyor 22. The chute 63 is provided withguiding strips 65 which divide it into individual chutes or channels forthe bottles whereby they are kept out of contact with each other and areguided into position between guide strips 66 extending lengthwise overthe conveyor The guide strips 65 on the chute are extended beyond thefloor of the chute so that the bottles are held in parallel spacedrelation as they drop from the chute onto the conveyor and pass betweenthe guide strips 66. Stops 67 are provided at the outer ends of thechute 63 to arrest the forward movement of the bottles as they drop fromthe chute.

The chute 63 is mounted to oscillate about the axis of a vertical shaft68 supported in a bracket 69 mounted on the forward end of an arm 71attached to the frame ii. The bracket 69 is adjustable lengthwise of thearm '71 by means of an adjusting screw 72 and is held in adjustedposition by bolts 73 A brace rod T l extends from the upper end of theshaft 68 to the inner end of the chute 63. The chute is oscillated bymeans of a cam 75 on the forward end of the shaft 39. Said cam operatesa rock arm 76 connected through a vertical shaft to a rock arm '77. Thelatter is connected through a spring buffer 78 and rod 79 to an arm 81fixed to the shaft 68. The arm 76 is held to its cam 75 by a spring '82connected to an arm 63 on the shaft 68. The cam 75 is so shaped that itwill cause the receiving end of the chute 63 to advance with thedischarging carrier 25 through a limited distance sutiicient to retainthe chute in register with the traveling carrier while the bottles slidefrom the carrier onto the chute. The chute then returns to register withthe next carrier. The rod 79 is adjustable lengthwise relatively to thearm 81 by means of an adjusting wheel 8-l threaded on said rod. wherebythe chute may be adjusted transversely into position to accuratelyregister with the carriers 25 while the latter are discharging.

Referring particularly to Figures 7 to 13 inclusive, the guiding stripsor ribbons 66 are mounted over the conveyor 22 and are of sufficientlength to keep the bottles separated during their travel through aconsiderable distance, so that suliicient cooling and hardening of thebottles is insured before they pass beyond said strips. The strips 66are preferably made of thin sheet metal, but may be of other materialand are anchored at their opposite ends respectively to transversesupporting bars 85 and 86 mounted on the frame 87 of the conveyor. Eachstrip 66 is provided at one end with a hook 68 to engage the bar 85.Pins 89 in the hooks 88 enter corresponding holes in the bar 85 to holdthe strips 66 properly spaced along said bar. Each strip 66 at itsopposite end has secured thereto a. head 90 provided with a slot 91 toreceive the bar 86. An adjusting screw 92 mounted in said head providesa means for adjusting the tension of the strip.

The bar 86 is connected to the conveyor frame by means of rods 93 (Figs.8 and 9). Each rod has a pivotal connection 94 with the frame andextends forward across the end ofthe bar 86. The latter is formed with agroove 95 to receive the rod. A tension spring 97 is interposed betweenthe ion ill)
